Sterling Auto Power Selector Switch

Features of Auto Power selector Switch AC32A

• 3 input 32 amp 110/230V a/c auto selector with remote control • Generator: up to 8000 Watt continuous 32 amp 230 volt a/c, fused, or other source • Inverter: up to 8000 Watt continuous 32 amp 230 volt a/c, fused or other source • Shore Supply: up to 8000 Watt continuous 32 amp 230 volt a/c, fused, or other source • Boat/vehicle electrics: the new simple power selector offers many new features not available on the older 16amp crossover switch, due to its digital control system. • 40 amp internal contactors: switches live and neutral with a 0.25 sec time delay between switch off and on to prevent wave doubling of the voltage and destroying sensitive equipment. • Multiple internal power sources: the system powers itself from each attached power supply; and not from the boats/vehicles D/C system. This is to ensure the system will work even if your batteries are flat. There is no point having an a/c selector switch powered from the D/C system, because if the D/C system fails then you cannot switch the system on to charge the batteries. The Sterling system obtains its control power from each input source, so preventing this problem. • Sequential switching: the unit has a simple operation mode; channel 1 is the priority, then channel 2, then 3. In other words if you allocate the inverter to channel 3 then plug in the shore power on channel 1, the switch will automatically switch the system to the shore power etc. • Lock out circuit: it is assumed that channel 3 would be your inverter (it could be another power supply depending on how you wire the system up). With a lower power inverter you may not wish your immersion heater or battery charger to work when the inverter is on line; so connected to this circuit is a small relay which can break the control circuit on an external contactor /relay block. This then allows you to wire the battery charger and immersion heater to a separate contactor block, preventing these items...
